Manchester City boss Roberto Mancini views Tottenham as serious title challengers, but hopes to deliver a hefty blow to their chances on Sunday.
The Barclays Premier League leaders host the Londoners in an eagerly-anticipated clash at the Etihad Stadium. City, who thrashed Spurs 5-1 when the sides met at White Hart Lane in August, can move eight points clear of Harry Redknapp's men by completing a league double.
"I think when you play against a top squad like Tottenham, (Manchester) United or Chelsea and you win it, your mentality improves. Your feeling is better, your confidence is better. I think that is very important, like when we beat Arsenal at home," said Mancini.
